• Remove workarounds for VSO-1664463 "/clr C++20 alignas emits error C3821 'managed type or function cannot be used in an unmanaged function' instead of falling back to native codegen".
• Remove workarounds for VSO-1152705 "_malloca_crt should suppress PREfast warning 6386".
• Remove workaround for DevCom-10334808 "Pointer operands are not correctly converted to the composite pointer type in three-way comparison".
• Followup changes after Avoid new warning C5267 for deprecated implicit copy ctor/assign #3497.
  • Enable the recently-added, off-by-default warning C5267 (for deprecated copy constructors and copy assignment operators) in the std and tr1 test suites to ensure that we remain clean. (libcxx contains too many occurrences in its own code to make this feasible.)
  • Fix aligned_type in P0220R1_any to avoid the warning. We need to work around VSO-1846195 "/clr alignas emits fatal error C1193: an error expected in yyaction.cpp(2971) not reached".
• Require Node.js 20.4.0 when building the Status Chart.
• Go back to Standard_D32ds_v5. This is an attempt to avoid stalled checks, although it probably won't help.
• Use PowerShell 7.3.5 to build the pool.
• New pool.
• VS 2022 17.7 Preview 3 contains Clang 16.0.5.
• Remove <xtree> workaround for VSO-761321 "Failure with local type alias in if constexpr condition", which was fixed at some point.
  • Logic cleanups for basic_string #3862 is removing the <xstring> workaround, so I'm not changing that here.
• 17.7 Preview 3 fixes Clang in VS 17.7p1 doesn't grok _addcarry_u64/_subborrow_u64 #3713, so we can revert the workarounds that I had to introduce in Toolset update: VS 2022 17.7 Preview 1 #3711:
  • _addcarry_u64/_subborrow_u64
  • LDBL_DECIMAL_DIG
  • tgmath.h
• Remove workaround for LLVM-62762 "32-bit-only misoptimization of printf calls on Windows", fixed by Clang 16.0.3.
• Style followup from Toolset update: VS 2022 17.7 Preview 1 #3711: Attach // TRANSITION, VSO-1690654 comment.
• Style followup from Toolset update: VS 2022 17.7 Preview 1 #3711: Attempt to improve formatting of _Can_construct_from_tuple_like.
• Remove workaround for VSO-1285779 "EDG rejects source_location intrinsics within consteval functions".
  • This was fixed on 2021-09-07 in VS 2022 17.0.
• Remove workaround for VSO-1268984 "New compiler intrinsics for Layout-compatibility and Pointer-interconvertibility Traits need to be understood by EDG".
  • This was fixed on 2022-03-07 in VS 2022 17.2.
• Remove workaround for VSO-657455 "EDG: dependent name in nested generic lambda not seen as dependent".
  • This was fixed on 2023-01-04 in VS 2022 17.5.
• Rerun clang-format 16.0.5, no manual changes.
• Add workarounds for VSO-1849453 "EDG mishandles is_pointer_interconvertible_base_of_v<EmptyBase, StatefulDerived>".
• Add workaround for VSO-1849458 "EDG mishandles is_layout_compatible_v<const int[], int[]>".
• Perma-workaround EDG behavioral differences in source_location::column().
  • I consider column() to be relatively unimportant and I don't think that these behavioral differences are worth reporting.
• Add workaround for VSO-1849463 "EDG silently rejects source_location::current() as a default argument".
